A blast of frigid air … a blizzard of ice … Toa Inika Matoro has arrived! The Toa Inika of Ice combines his elemental cold power with pure lightning to stop the Piraka. He carries an energized ice sword, a zamor sphere launcher, and wears the Kanohi Iden, the Mask of Spirit.

They came to Voya Nui as Matoran villagers on a rescue mission. Then six bolts of lightning from the Red Star transformed them into the newest team of Toa -- the Toa Inika! Their goal is to find the powerful Mask of Life, the Ignika, and use it to save the life of the Great Spirit Mata Nui.
Matoro is sometime unsure just what he is doing as a Toa -- after all, he is not an athlete or a warrior or an inventor, he is a translator. Strange things have been happening to him ever since he left Metru Nui to go to Voya Nui, leading him to think some unknown destiny is waiting for him here. In the meantime, he is testing the limits of his powers and slowly gaining more confidence in his new role. He carries an Energized Ice Sword. Matoro has been chosen by the Ignika to be its guardian and carrier, as the Inika continue to try to retrieve it.
Although the Inika successfully obtained the Ignika from Vezon and Kardas, the Mask escaped from them, causing it to sink to the waters around Mahri Nui. The Inika travel down a white-stoned passageway with hopes to retrieve the mask yet again.
